THRUST-BEARING.

Application filed April 8.

. whereby centrifugal action will draw the oil gravity.,

from around the bearings and cause it to circulate over cooling: coi-ls so as to increase the bent radiation.

lVith these and other ol'xjcets in View, the invention czmsists in the construction. coni.-

binnton and arrangement of parts as will be hereimrfter fully described', illustrated' in the aeemnpnnying drawing and pointed out in the claims heren-nto appended.

1in the drawings:

is a sleeve collar which may be suitably avltachedi' to :my shaft. B' is a. radial' orifice which extends from the outer face ot' the sleeve collarI A tothe inner face of the saine thus forming a 'discharge opening from the inner cli-amber C. D is a pipe extension whichv muy be inserted i-n the outer end of orice Bf if the circulation of thev oil is' to be further increased. over that cai-usedl by the centrifugal. o the sleeve collar without this extensioI-iV D'.

Ef is- :t rotatable diislc which rotates in con nec-'tion with. the sleeve A. This disk is pr0- vided with zur iumulnr cup-slumped groove F on its inner side. In the d-rwwing I show by w unisi-'ow line the directionA o the flow of the Y oil'. lit will be noticed' that the discharge liront the extension Dl will strike the inner side of the cup-shaped' girotqve F their after pnssingoever the groove F it will follow upwnrdily over the top of the disk E. vVhile `passing-orar the grooveV F and before striking-the upper edge ol'f'thedis'k E, any foreign matter which might be in the oil will drop into the 2groove F und muy be removed when the machine is stopped'.-

G is the? housing' around the bearingv and is provided with a emp H. 'After the oil reaches. the top'l of the disk E it will bedmaiwn against the caj- H and follow the inner side-.of'this cmpdownwwrdly due to Specification of Letters Patent.

1919. Serial No. 288,535.

Patented Deo. 2, 1919.

J indicates n series of cooling coils suitably arranged inside the housing G s0 that.

the oil after running down the inner side of the cap H and over the lip Hll drops on the top of the series of cooling coils J which extend above the' oil lev'el in theoil bath.

K is u concentric wall formed as a. part of the housing G und is provided with suitable ports K1 near its lower portion. The oil from around the cooling collars J, afteizbeing: cooled,- is drawn through the ports K1 and renters the inner chamber C by means i of an opening L.

Before passing: through the ports K1 any foreign matter that may be in the oil will he allowed to deposit in the lower part of i this outer chimrber in which the cooling coils are situated. v

'A further flow of oil is noted by the double arrowline?V This How passes from the inner chamber- C and out between the rul'ibi-ng surfaces Ml and M2. it then returns throw-:gh the opening L to the inner chain-- ber C.

N i-s'theA oil intake' pipe suitably connected with the housing (if.

From the foregoing it is'A thought that the construction of my linvention will be clearly understood, :md therefore a vmore extended explaination' has been omitted.

'hat I elfzri-m as new, is,.-

-1. A thrust bea-ring consisting of a, sleeve,

collar suitably positioned on a.' shaft, a disk suitably positioned on' said collar, a. housing pro-vided with a suitrble member whose upper face acts as n rubbin 4surfaoe with, the lower portion of said co livr,l a concentric wall ext-ending upwardlyjrom the bose l 2. A' thrust bearin consisting, of a. 4housing having a. suitab e cap, a. sleeve collar vmounted. on. a. shaft and adopted to rotate inside'saiid housing, a disk positioned onsaid! sleeve collar, said: disk having im annular 11p-turned groove on vits inner face and its' outer woll bent inwfrgrdlyatthe top, said sleeve having a radial oriice near its lower end, a tube extension adapted to engage in the outer end of said orificeysaid housing having a concentric wall extending upwardly 54 from its base, said wall having suitable yintake ports, a series of cooling coils suitably arranged between said wall and the outer .wall of said housing, a rubbing block suitably positioned in said housing so that the lower portion of said collar acts as a rubbing surface thereon, an inner wall positioned inwardly from said rubbing block, an intake orifice in said block and an intake connection engaged at the outside of said housing.

3. A thrust bearing consisting of a sleeve .collar provided with vsuitable rubbing surface at its lower end, 'said collar beingr-suitably positioned on a shaft, a disk rotatably mounted on said collar, a housingvcovering the lower portion of said sleeve and said disk and a cap suitably engaged with said housing and .covering the upper por- .'tions of said collar and said disk, said housing being provided with an upwardly extending concentric wall and a rubbing block l having an upwardly extending wall attached at its lower inner end. suitable cooling coils between said concentric wall and the outer wall of said houising7 an intake pipe on the outer .side of said housing. suitable ports through said concentric wall and an orificeI through said rubbing block permitting passage of the oil to the inner chamber from bctween said rubbing block and said inner wall, an orifice through the lower end of said collar and adapted to draw the oil from said inner chamber due to centrifugal action and discharge it on said disk where it. will overflow at the upper edgein a thin lin strikin the cap portion .Off said housing over whic 1 it flows'downwardly dln` to gravity and is passed over said coolingr coils, part of said oil engaging between the rubbing surfaces without being drawn through said collar orifice.

In testimony whereof l affix my signature in the presence of two witnesses. A
